What feature are you suggesting?

[ you should be able to hand drink from cauldrons. the condition of the water would be based on where you got it. ]

Why should it be added?

[ convenience? I just thought it was a bug initially but I don't see anyone online talking about it as a bug, or at all, so I figured it was intentional or overlooked. ]

We're not support hand drinking any more than what's already there. There's a reason it's disabled by default, because it's not meant to be used at all, and is only there so people don't whine to us to re-add it.
